RODI before or after water softener?

[mpatterson42]

I live in Phoenix and we have REALLY hard water. I just tested it and it came out to 17GH (300ppm). I also have a water softener that's used for all the water inside the house. Testing that it comes out to 3GH (53ppm). KH is 7 (125ppm) regardless if I use soft or hard water.

Softener is a Rheem Preferred Platinum 42,000 Grain Water Softener and I use salt crystals in it.

I'm planning on setting up an RODI filter to make my own saltwater, but I'm not sure if I should use it before or after the softener, it's easy enough to do either. Hooking it up before the water softener the RODI filters might have to work harder with how hard the water is, but I'm worried that the water coming out of the softener is either too soft or has other things stripped out that might be useful for saltwater.

Thanks for any advice.

The rodi wil strip out almost everything. My vote would be after the softener

You want everything stripped out of the water that can be. So when you add your salt mix you get everything added back in known quantities.

After softener, since the softener helps bring the hardness down.

I live on a well and use, in this order, mechanical filtration, green sand filter, softener, then rodi. We run around high sulfur, and have tested up to 1,000 ppm during spring melt.
